Evaluation of the ScalpelCric Set and Comparison With Two Further Techniques of Cricothyrotomy

During a cannot ventilate cannot intubate situation surgical airway is the last rescue option. Especially in the prehospital setting the airway management seems to be more difficult than in a hospital setting. Nearly all emergency physicians have a limited experience with cricothyrotomy and it is a unclear what method should be taught for this lifesaving procedure, due to lack of data in humans. The aim of this study is to compare the performance of medical personnel (medical students, paramedics, trainee anaesthetists and consultants) in establishing an emergency surgical airway on a plastic laryngeal model and in a porcine laryngeal model using the Scalpel Bougie technique, the Seldinger technique and the common surgical technique. Furthermore the investigators want to elucidate whether the training of the 3 techniques has an influence in the decision making of the preferred technique in a subsequently simulated cannot ventilate cannot intubate scenario.
